The Cyber Resilience Review (CRR) is an assessment method developed by the United States Department of Homeland Security (DHS). It is a voluntary examination of operational resilience and cyber security practices offered at no cost by DHS to the operators of critical infrastructure and state, local, tribal, and territorial governments. The CRR has a service-oriented approach, meaning that one of the foundational principles of the CRR is that an organization deploys its assets (people, information, technology, and facilities) to support specific operational missions (or services). The CRR is offered in a facilitated workshop format and as a self-assessment package. The workshop version of the CRR is led by a DHS facilitator at a critical infrastructure facility. The workshop typically takes 6–8 hours to complete and draws on a cross section of personnel from the critical infrastructure organization. All information collected in a facilitated CRR is protected from disclosure by the Protected Critical Infrastructure Information Act of 2002. This information cannot be disclosed through a Freedom of Information Act request, used in civil litigation, or be used for regulatory purposes. The CRR Self-Assessment Package allows an organization to conduct an assessment without the need for direct DHS assistance. It is available for download from the DHS Critical Infrastructure Cyber Community Voluntary Program website. The package includes an automated data answer capture and report generation tool, a facilitation guide, comprehensive explanation of each question, and a crosswalk of CRR practices to the criteria of the National Institute of Standards and Technology (NIST) Cybersecurity Framework. The questions asked in the CRR and the resulting report are the same in both versions of the assessment. DHS partnered with the CERT Division of the Software Engineering Institute at Carnegie Mellon University to design and deploy the CRR. The goals and practices found in the assessment are derived from the CERT Resilience Management Model (CERT-RMM) Version 1.0. The CRR was introduced in 2009 and received a significant revision in 2014.
